I hear the real invoice does not include freight and advertising fees and then I hear the real invoice does include those.

Which is the right invoice? Those make a big difference.

It doesn't matter because the dealer is only making the holdback on the car as profit. Holdback isn't a lot on a Camaro so the dealers aren't getting rich selling Camaros at invoice. I know everyone wants a good deal but dealers have to make profit or they can't stay in business.

What you want is something that's fair for you and fair for the dealer. Anything under invoice is fair to both.
